QUESTION 1A concrete floor slab measuring 6 m x 3 m is simply supported on one side brick load-bearing walls along the 6 m sides. The concrete slab is 200 mm thick and reinforced at the bottom as follows. a. Main reinforcement (short span i.e the bars are parallel to the short span), Y12, shape code 34 @ 125 mm centre to centre,b. Distribution reinforcement (long-span i.e the bars are parallel to the long span), Y 10, shape code 20 @ 300 mm centre to centre,c. Concrete cover, 30mm,d. Concrete strength, 40MPa. Draw the reinforcement layout for this slab, in plan and section, indicating all thereinforcement and necessary information required by the contractor. Calculate and indicate the number of bars required on your drawing. You do not need to calculate the bar lengths and the curtailment. Neat drawing please

Please answer the problem below. Thank you very much Show your solution
Determine the numbers of rebars required for a RC beam (h=400mm, b=700mm) carrying a factored moment of 796 kPa. The concrete used has a compressive strength of 28MPa, while steel yields at 345MPa. Assume single layer of reinforcements (compression and/or tension side) and do not check for rebar spacing anymore. Other parameters: Cc = 40mm db = 20mm ds = 10mm Provide illustration if necessary and answers must be in 3 decimal places.
Please answer the problem bellow thank you very much, Asap.
Wood planks are used on each working level. The deck width/bearer span is 5 ft.. The bearers and posts are standard pipe and the pipe material is A36 steel with a yield stress of 36,000 psi and modulus of elasticity of 29,000,000 psi. Bearers are to be located at a vertical spacing of 10 ft (largest, lowest post height). Posts are to be 7 ft oc (plank length) parallel to the building wall and 5 ft apart (bearer length) perpendicular to the building wall. There are four working levels and the anticipated scaffold loading will be med duty. A. Assuming the ultimate bending strength of the planks is 3,800 psi (apply a 4:1 F.O.S.), determine the required minimum plank thickness to the nearest 100th. B. Based on the bearer material provided, what is the minimum pipe size that can be safely used? See Appendix 2 in your textbook for steel pipe properties. C. Based on the post material provided, can a 2” standard pipe be used safely? Be sure it satisfies buckling stress conditions only.

37 A simply supported beam 300 mm wide, 500 mm deep and spans 5.5 m supports a service super imposed dead load of 8 kN/m and service live load of 7 kN/m. Concrete strength f’c = 21 MPa and steel yield strength fy = 415 MPa. Concrete cover to bar centroid is 70 mm. Determine the required amount of tensile reinforcement in mm^2 as per provisions of NSCP 2015. Write your final answer to the nearest whole number.
